{"id":"DEBIAN-CVE-2025-38240","details":"In the Linux kernel, the following vulnerability has been resolved:  drm/mediatek: dp: drm_err =\u003e dev_err in HPD path to avoid NULL ptr  The function mtk_dp_wait_hpd_asserted() may be called before the `mtk_dp-\u003edrm_dev` pointer is assigned in mtk_dp_bridge_attach(). Specifically it can be called via this callpath:  - mtk_edp_wait_hpd_asserted  - [panel probe]  - dp_aux_ep_probe  Using \"drm\" level prints anywhere in this callpath causes a NULL pointer dereference. Change the error message directly in mtk_dp_wait_hpd_asserted() to dev_err() to avoid this. Also change the error messages in mtk_dp_parse_capabilities(), which is called by mtk_dp_wait_hpd_asserted().  While touching these prints, also add the error code to them to make future debugging easier.","modified":"2026-08-27T23:05:29.555980423Z","published":"2025-04-18T07:15:43.510Z","upstream":["CVE-2025-38240"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-38240"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.25-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-38240.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.25-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-38240.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
